I honestly love pittys, however how the dog reacts depends on how it is brought up. Pits are strong, big dogs (most of the time) that definitely need to be controlled and put in their place at a young age. If you let a pit (or any dog) be excited, nippy, and aggressive as a pup, it might be cute at the time, but that dog will grow to be very strong and it wont be as cute when they're nippy at a young child or dog. This has to do with any dog, but it's important with the Pit because of the breed. A mother would rather put down a pit instead of a small dog for biting their child, no matter which one is worse. I think it's the harsh reality that the owners have to face and deal with. I have a lot of respect for people who know how to control their dog.
I LOVE the dogs, I have a friend who is very strict with her pit (she has to be, that dog is huge and very strong) I love the look of the dogs and I would rescue/adopt one in a heartbeat if it was friendly with kids and cats.
